Today in math we were working on lines of symmetry and planes of symmetry.

Lines Of symmetry:A line of symmetry divides a figure into two identical parts.Each part is the reflection image of the other part.A baseball diamond has one line of symmetry.Ex:A pentagon has 4 lines of symmetry.

Planes of symmetry:Many three dimensional objects are symmetrical.The left hand and right hand halves of this Canadian aircraft are the same.Ex:An Isosceles triangular prism has one line of symmetry.
